"Google is commodifying the audience of specialist publishers and limiting their ability to generate advertising revenue. Data aggregators attempt to sell audiences at a steep discount to the original source, for example, access to 75 per cent of The Wall Street Journal demographic at 25 per cent of the price, thus undermining the business model of the content creator. This process is at a relatively early stage and needs constant monitoring to ensure that abuses are halted and that there is a fair return for newspapers, publishers and other investors in original content."
